NICE!!!!
Really do you have to replace the tire set for every 15k to 20k? Do you like to spin the tires?

Just replaced my factory Bridgestone Potenza RE50A tires at just over 26k miles.They were in bad shape! I like to do "quick starts" from a stop, but I don't do it often. I went with the Hankook v12's too. Staggered tires go quick. One reason is they can't be rotated. I will feel fortunate if the new tires last as long as the originals.
